GUTLERY KNIFE-HOLDER.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed January 10, 1907.. Serial No. 351,713.

To all whom it may concern:

Be it known that I, ERNEST POTTER, a citizen of the United States, and a resident of South Meriden, in the county of New Haven, and State of Connecticut, have invented cert'ain new and useful Im rovements inCutlery Knife-Holders, of which the following is a specification.

My invention relates to an improved knife hold er adapted for use in connection with cutlery grinding and cutlery olishing machines. While capable of holding (IllVGS of every description, it is particularly adapted for holding stub and round tang knives.

To enable others to understand my invention, reference is had to the accompanying drawings in which: t

Figure 1 represents an upper plan view of the holder showing the gri ping jaws open Fig. 2- is a side elevation of the holder: Fig. 3- a section on a aof Fig. 1 Fig. 4- is. a broken section of the holder and. knife blade therein with the jaws closed.

1 represents the base of j the holder, which base may be attached to the reci ro-' cating carriage or slide of a cutlery grin in or polishing machine, or it may be an integra part of the same.

2- is a bed or support for the face of the blade 3-', and is attached to the base by screws 4. This bed can, if desired, form an integral part of the base 1.

5- is a ledge or flange rising from the bed to form a support for the back of the knife blade.

, 6- is the stationary jaw having therounded lip 6 and curved recess or depression 6"- adapted to receive the neck 3 of the blade.

7- is the movable jaw pivotally supported on the bolt 8 and having a corresponding lip -7 and depression 7.

9- is abracket secured by the screw10 to the-stationary jaw 6.

11 is a stud projecting from the bracket to form a bearing on which the hub of the handle lever 1 2 is j ournaled.

13 is a spring cam secured to the handle lever by the screw 14 whose free end is located between the inner face of the hub of the handle lever and the outer face of the bracket -9-,. whichfreeend is provided embrace the stud 11. 16- are jam nuts on the outer end of this stud to regulate the tension on the cam 13-.

17- &- 18 are adjustable set screws projecting through the jaws whose points are adapted to v engage the tang 3 of the knife when the knife is in the grip of the jaws, and -19 and -20 are jam nuts for said screws.

Operation. The knife blade is placed on the support 2, when the jaw 7 is in open position as shown at Fig. 1. The handle lever is then rotated in the direction of arrow -b of Fig. -2 until it strikes against the stop 22. Turning the handle lever in the direction as stated, will bring the outer face of the cam forcibly against the outer face of the jaw -7 and the closing of this jaw will carry the knife blade against the ledge 5 and clamp the neck of the blade firmly as shown at Fig. 4. The set screws 17 and 18-, being previously adjusted, grip the tang so as to balance the grip of the jaws and also keep the blade level during the operation of grinding or polishing. When the andle lever is thrown around against the stop 22, the spring 23 will open the jaw -7, which open move ment is limited by the contact of the opposite end of the jaw with the stop pin 24.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a knife holder of the character described, a support for the blade, jaws adapted to grip the neck of the knife, one of said jaws stationary and the other movable, adjustable set screws adapted to engage the tang of the knife, means for operating the movable jaw, for the purpose set forth.

2. In a knife holder" of the character described, a support for the blade, jaws adapted to grip the neck of the knife, one of said jaws movable and the other stationary, adjustable means for engaging the tang of the bladefa handle lever, a support therefor, a spring cam adapted to contact with the movable jaw, for the purpose set forth.

3.-In a knife holder of the character described, a support for the blade, jaws adapted to grip the neck of the knife, adjustable means on said jaws for gripping the tang of the knife, one of said jaws stationary and the other movable, a handle lever, a bearing on Signed at So. Meriden in the county of which the handle lever is journaled, a sup- New Haven and State of Connecticut this port for said bearing, a spring cam secured to 14 day of Dec. A. D. 1906.
